POWDER-DISTRIBUTER.

SPECIFICATION formingpart of Letters Patent No. 247,124, dated September 13, 1881. Application filed June 27, 1881. (No model.)

To all whom itmay concern:

Beit known that I, JOSEPH S. SMITH, a citizen of the United States, residing in (Jolmar, Montgomery county, Pennsylvania, have in- Vented certain Improvements in Powder-Dis tributers, of which the following is a specificalion.

The object of my invention is to construct a simple and efiective device for uniformly dis- IO tributing powdered substances, such as fertilizers, compoundsfordestroyingpotato-bugs, or other powdered materials used in agricultural operations; and this object I attain in the manner hereinafter set forth, reference being had to the accrnnpanyi'ng drawings, in

which- Figure l is a perspective View of one form of my improved powder-distributcr; Figs. 2 and 3, transverse and longitudinal sections of the same, respectively; Fig. 4, a longitudinal section of another term of the device, and Fig. 5 aplan view of Fig. 4.

A is a receptacle ofany suitable size or shape, having at the top ai'eed-opeuing, and commua chamber, B, contained within a segmental casing, D, secured to or forming part ot'thecasingot the receptacle A. Thecasing I) has on the under side a perforated plate, 0, and in the ends of said casing are formed bearings for the shaft 1) of a spiral brush, E, which is driven in the direction of the arrow either by a crank applied directly to the end of the shaft 0 or by means of suitable gearing, as described hereinafter. As the brush is rotated the powdered material falls from the receptacle A through the slot aand into the spaces between the spiral rows of bristles forming the brush, the

I latter extending continuously from end to end 46 of the brush, thereby effecting the uniform and thorough distribution of the powder through the-perioratious in the plate r. Said plate is detachable, so that plates ol.' dili'erent degrees of fineness may be used, in. accordance with he charaoterot'thematcrial to be distributed. In the device shown in Figs. 1, 2, and J; the receptacle Ais furnished with a shoulder-strap,

c1, and handle so that it is adapted to be car- .ried upon one arm, the brush-shaft being rotated by means of the gearing shown, which is operated by the other hand as the person carrying the device walks along the row oi plants to which the powder is to be applied.

When adeviceot' ,g'reatercapacity is required I prefer to adopt the form shown in Figs. 4 and 5, in which F represents a frame mounted upon wheels G, the latter being secured to a shaft, H, which turns in hearings on the frame, and is furnished with a pulley, f, a belt from which passes round a pulley, g, on a shaft, J, also adapted to bearings on the frame F. The shaft J projects laterally beyond the frame F on each side, and to these laterally-projecting portions of the shaft are adapted cog-wheels m in, one of which gears into the pinion a on the brush-shaft of a dis't-ributer, A, at one side of the machine, the other wheel in. gearing into a pinion on the brush-shalt of a similar distributor-Act theo ipositc side ot the machine. As the mounted frame, occupying the space between two rows of plants, is pushed over the ground the distributors are carried over the rows of plants, and the brushes of said distributors are actuated by the belts and gearing so as to uuitormly distribute the powder over the plants. The distributors are carried bybars 10, which are adapted to suitable guides on the frame F, and are capable oi sliding in .said guides, so that the distributors may be adjusted laterally in respect to the frame F, in order to adapt the machine to diit'eren tly-spaced rows, the bars '20 being secured in position ai ter adjustment, so as to firmly retain the distributors.

The cogavheels m are also adjustable laterally on the projecting portions of the shaft J, suitable set-screws or other means being used to secure them to said shaft. 7

It is advisable in most cases to provide the frame F with alarge box or receptacle for Corr taiuing a supply of the powdered material, from which the receptacles A can be repleir ished as desired without. the necessity oi i'requeutly returning to the main sourccot' supply. It isadvisable, also, to provide theeog-wheels m or pinious It with clutches,

ac; toe brush 2 ill l'ihili y i of either of ihe distributers can be thrown out of gear and the distribution of powder stopped, when desired, Without stopping the forward movement 0 the machine, so that the application of powder to either or both rows of plants can be governed as desired.

Instead of usingelutches, the receptacles A may be moved longitudinally on the frame F, so as to carryeither 01: the pinions u out of gear with its wheel on when it is desired to stop the operation of the brush.

I claim as my invention- Apowder-alistributer in which are combined the receptacle A, the (listributing-chamber B,

communicating with said reoepipacie, e115: hex" 15 in a easing, l), with performer? portion c, and the brush E, conforming to the casing D, and having brush in eteriel arranged thereon in spiral. 'rows, which extend eon 'neoesly from end to end of the brush e In tesiimohy whereof I have signed in y to this speoifieation in the presence of enhseribing' witnesses.
